1. I cannot find a way of selecting individual dimensions and changing the precision lets say from 0.00 to 0.000 for these particular dimensions only without affecting all the rest of the dimensions in the drawing - could an option be added for doing this in the property editor or not?

2. Would it be possible to add an option in the drawing preferences so that automatically a symbol is added at the correct placement fo all dimensions, in this case a tolerance plus/minus symbol?
